FIELD OF THE INVENTION

The present invention relates to herbicide. Specifically to a kind of uracil compounds containing isoxazoline ring and the uses thereof.

BACKGROUND OF THE INVENTION

The research of uracil derivatives as herbicides began in the 1960s and peaked in the 1990s. Although the development of uracil herbicides were seldom reported, some patents of uracil derivatives were often disclosed. Isagro Ricerca disclosed the following general formula in WO2004056785. However, the herbicidal properties of these known compounds are not always entirely satisfactory.

Wherein: Q₁ was 5-membered heterocycle such as oxazolyl, thiazolyl, benzoxazolyl, benzothienyl, benzothiazolyl, etc. Q₂ was F or H.

Even though some similarity can be observed between published compounds in the prior art and the present invention compounds, the compounds having the structure of general formula (I) were different significantly from those in prior art, and have good herbicidal activity as well.

SUMMARY OF THE INVENTION

In order to discover and develop new herbicides for solving the increasing problem of resistance, the present invention provides a kind of uracil compounds containing isoxazoline ring and the uses thereof.

In order to achieve the above object, technical solution of the present invention is as follows:

The present invention provides a kind of uracil compounds containing isoxazoline ring having general formula (I):

The compounds having general formula (I) in present invention can be prepared from amino-compounds III according to the literature method, such as U.S. Pat. No. 5,336,663, U.S. Pat. No. 6,992,044, WO2001083459, etc.

The carboxylic acids(I-2,I-2′) can be prepared from the compounds I-1 or I-1′ according to the literature method when R₈ or R₉ is CO₂C₂H₅, followed by the further reaction to form carboxylate compounds I-3 or I-3′ and amides according to the literature method, the references such as US20060223848, WO2012130798, WO2014048827, WO2014048940, etc.

The alcohols compounds I-6 or I-6′ can be prepared by reaction of the compounds I-5 or I-5′ with acetyl chloride in methanol referring to synlett, 2005, 10, 1527-1530. And then the compounds I-7 or I-7′ was obtained by reaction of alcohols compounds I-6 or I-6′ with R₁₂-X which is acyl halide, benzyl halide, halogenobenzene or halogenoheteroaryl under basic conditions.

The reaction was carried out in proper solvent and the proper solvent mentioned may be selected from benzene, toluene, xylene, acetone, tetrahydrofuran, acetonitrile, N,N-dimethylformamide, N-methylpyrrolidane, dichloromethane, chloroform, dichloroethane, ethyl acetate, etc. The reaction can be carried out under base or no base conditions, and the reaction can be accelerated in the condition of base. The proper base mentioned may be selected from alkali metal hydride, such as NaH, LiH, NaNH₂, and so on; or alkali metal hydroxide, such as KOH, NaOH, and so on; or alkali carbonate, such as K₂CO₃, Na₂CO₃, and so on; or organo-alkali, such as pyridine, 4-dimethylaminopyridine, triethylamine, N-methylpyrrolidine, N, N-diisopropylethylamine, and so on. The proper temperature mentioned is from −10° C. to boiling point of solvent, normally the temperature is at 0 to 100° C. The reaction time is in the range of 30 minutes to 20 hours, generally being 1-10 hours.

R₁₂-X is commercially available. The X is leaving group selected from Cl, Br or I.

The amino-compounds III can be prepared from nitro compounds IV according to conventional methods by reductants, such as Fe, Zn, Pd/C, SnCl₂, and so on, referring to EP2044006, US20070155738, European Journal of Medicinal Chemistry, 2013, 65, 32-40, Synlett, 2010, (20), 3019-3022, Heterocycles, 2008, 75(1), 57-64, etc. The nitro compounds IV can be prepared from aldehydes VIII by three steps reactions according to the literature method, such as J. Agric. Food Chem. 2005, 53, 8639-8643 or WO2006090234.

Each group of formulas is as defined above except special explanation.

The present invention compounds can effectively control weeds, such as Echinochloa crusgalli, Setaria viridis, Cyperus difformis, Juncellus serotinus, Digitaria sangunalis, Arthraxon hispidus, Abutilon theophrasti, Zinnia elegans, Amaranthus retrofluxes, Portulaca oleracea, Xanthium sibiricum, Solanum nigrum, Cassia tora, Hibiscus trionum, Glycine soja, an so on. They can effectively control weeds even at lower doses. The present invention compounds are also safe to wheats, corns and rices, and can used as herbicides in agriculture fields. Therefore, the present invention also includes the use of the compounds having general formula (I) as herbicides to control weeds.

TEST OF BIOLOGICAL ACTIVITY Example 18 Bioassay of Herbicidal Activity in Greenhouse

Determination of herbicidal activity of compounds of the present invention against weeds was carried out by the following procedures:

Seeds of monocotyledonous and dicotyledonous weeds were sown in nutrition soil in paper pot (7 cm diameter), covered with soil in 1 cm and grown in the greenhouse under good growth conditions (temperature, atmospheric humidity, water supply). The compounds of the present invention as emulsifiable concentrate, were applied in pre-emergence and post-emergence treatment by track sprayer (Engineer Research Ltd., pressure 1.95 kg/cm², volume 500 L/hm², track speed 1.48 km/h). Pre-emergence treatment was conducted after seeding 24 hours and post-emergence treatment was done when the respective weeds reached predetermined leaf stage (grass weed 2- to 3-leaf stage, broad-leaf weed 2- to 4-leaf stage), the state of growth of the respective weeds were visually observed to determine the growth inhibition rate(%) in accordance with the following evaluation standard.

Growth inhibition rate (%): 0=no discernible action: 100=all weeds dead or not emerged.

The results of general screening showed that compounds 4, 5, 6, 7, 8, 10, 15, 16, 17, 22, 23, 26, 35, 42, 43, 45, 46, 50, 54, 55, 66, 67, 83, 88, 90, 96, 99, 282, 284, 286, 290, 320, 321, 323, 324, 328, 329, 332, 333, 345, 366, 396, 397, 398 had a good pre-emergence and post-emergence herbicidal activity against broad-leaf weeds and grass weeds at 1000 g a.i./hm².

Example 19 Crop Safety Study in Greenhouse

Seeds of soybean, cotton, maize, wheat and rice were sown in nutrition soil in paper pot (9 cm diameter), covered with soil in 1 cm and grown in the greenhouse under good growth conditions (temperature, atmospheric humidity, water supply). The compounds of the present invention as emulsifiable concentrate, were applied in pre-emergence and post-emergence treatment by track sprayer (Engineer Research Ltd., pressure 1.95 kg/cm², volume 500 L/hm², track speed 1.48km/h). Pre-emergence treatment was conducted after seeding 24 hours and post-emergence treatment was done when the respective weeds reached predetermined leaf stage (soybean and cotton at 2- to 4-leaf stage and maize, wheat and rice at 3-leaf stage), the state of growth of the respective crops were visually observed to determine the safety in accordance with the following evaluation standard.

Safety rating scale (%): 0 means no damage to crops; 100 means to kill crops completely.

The results showed that wheat, maize and rice have good safety to compound 43, 45, 46, 83 at 7.5-37.5 g a.i./hm² with pre-emergence and post-emergence application.

Example 21 Field Trial

The field trial was conducted in an orchard located at Liaoyang city, Liaoning province, China; the orchard planted mainly apple trees and almond trees, plum trees and pear trees as well, weeding control were conducted three times one year by application of paraquat. Weeds were distributed uniformity and moderate density, mainly of broad-leaf weeds including Conyza canadensis (L.)Cronq., Sonchus brachyotus DC., Polygonum aviculare L., Humulus scandens (Lour.) Merr., Ixeridium sonchifolium (Maxim.) Shih, Galium aparine L. var. tenerum Gren.et (Godr.) Rebb., Rumex japonicus Houtt. and Metaplexis japonica (Thunb.) Makino, partly of grass weed was Digitaria sanguinalis (L. ) Scop., average height range was between 30 and 40 cm. sprayer was knapsack hand-operated sprayer(AGROLEX HD400) produced by AGROLEx PTE Ltd., spray volume was 675 L/hm², processing date was Jul. 3, 2015. On the 15th day after application, weeds were visually observed to determine the growth inhibition rate(%).
